In July 2001, Dunkirk blast furnace 4 achieved a 13 years and 9 months long campaign with a 41.7 millions tons hot metal cumulative output. The relining works had been scheduled within a 65 to 75 days period for a total cost over 150 millions Euros. The objectives of the next campaign are : a daily production over 10,800 tons, a blast furnace life over 20 years without any intermediate repair, a significant improvement of the working conditions and a major reduction of the environmental impact.

Since 1953, under successive 5-year development plans, the structure and the production level of the Chinese steel industry has considerably changed. Although the share of flat products has increased, China remains a net importer of these products and other high value added products. In connection with the development of the consuming industries, the Chinese steel industry is undergoing important transformations, in structure, technology, capacity and efficiency.
